What is Bootloader unlocking?

It is a fragment of code that ensures your device starts or boots up correctly. We can kind of think the bootloader as an intermediary that checks that the hardware and the software are in sync to perform perfectly for the user.

A bootloader on a smartphone is locked by default by the OEM. Your device may lose its warranty when it is unlocked. It is kept locked so as to encourage people to use the device in its stock form and do no customization on it. However, people are more into rooting and trying out custom ROMs on their devices. So, to achieve that they unlock the bootloader of the device.
